MACROBERT, C J  y  STERGIANOS, T J. Establishing competent ground conditions with the DPSH. J. S. Afr. Inst. Civ. Eng. [online]. 2023, vol.65, n.1, pp.2-6. ISSN 2309-8775.  http://dx.doi.org/10.17159/2309-8775/2023/v65n1a1.

Insufficient information is currently available to fully understand the mechanism of rod friction in DPSH (Dynamic Probe Super Heavy) probing. Consequently, a method is proposed to distinguish profiles in which friction results in excessive blow counts based on normalised profiles. While friction-impacted DPSH profiles are difficult to interpret, those unaffected by friction show better equivalence to SPT (Standard Penetration Test) profiles, especially if used to screen for competent (SPT blow counts > 30) ground conditions.
